Here's mine and it does in fact yield the same six numbers!  Since I am
learning Python, these challenges are important to me.  I really appreciate
people posting "problems" that we can solve.  I enjoy the solutions even
more.  

def reverse(n):
    rev = 0
    while n > 0:
       rev = (rev * 10) + (n % 10)
       n = n / 10
    return rev


def main():
   for i in range(1, 1000000):
       j = reverse(i)
       if (i <> j) and (i % 10 <> 0) and (i % j == 0):
           print str(i)

main()
